Benefits of technology

The invention is a system and method for measuring the response time of a touch screen on a touch screen device. This is done by recording the interaction between a robotic member and the touch screen, and analyzing the data to calculate the latency of the touch screen response. The system includes a video camera and a processor that correlates the data from the recording to the interaction. The technical effect of this invention is to provide a more accurate measure of the user experience of touch screen based devices, allowing for improved design and development.

Problems solved by technology

Conventionally, display response rate may be hard to accurately determine.
In other examples, display response rate may be determined by monitoring human interaction with the device, which may introduce error or inaccuracy, as the human interaction may not be consistently identical and repeatable without variation.
Conventional systems for measuring display response rate of touch screen devices suffer from these and other drawbacks.

Embodiment Construction

[0019]FIG. 1 illustrates a system 10 configured to determine a latency of response of a touch screen display on a touch screen device (not shown). System 10 may include a housing 20 with a holder 30, and a robot 40 operatively coupled to housing 10. Holder 30 may be configured to hold a touch screen device in a fixed manner. Holder 30 may hold touch screen devices of different sizes. For example, holder 30 may have fixable members or fasteners (not shown) that rigidly hold the touch screen device. The fixable members may include, for example, clamps that attach to the device, braces that hold the device at one or more of the device edges, adhesive at a top surface of the holder that attaches to a surface of the touch screen device opposite the touch screen display, or one or more combinations of these or other types of fixable members or fasteners.

[0020]Robot 40 may include a movable physical structure such as, for example, a robotic member 42, one or more sensors (not shown), one o...

Abstract

One aspect of the invention relates to an exemplary method for measuring latency of display response of a touch screen on a touch screen based device, comprising recording, by a video camera, an interaction with the touch screen, correlating, by a processor in operative communication with the video camera, data retrieved from the recording to the interaction; and determining, by the processor, a latency of the response of the touch screen to the first contact. An interaction may comprise at least a first contact between a member and the touch screen, and a response of the touch screen to the first contact, including at least a first change of a frame of a display of the touch screen.

Description

FIELD OF THE INVENTION[0001]The invention relates generally to a system and method for objectively measuring user experience of touch screen based devices via external mechanisms.BACKGROUND OF THE INVENTION[0002]User input and interaction with mobile and embedded devices typically occurs, for example, via a touch screen display on a device. A display response rate for a display (e.g., a touch screen found on devices such as a phone, tablet, and / or other mobile or embedded devices) may be a latency between a typical user action (e.g., touch, swipe, button press, and / or other contact with the touch screen) and a resulting reaction appearing on the device's display.[0003]Conventionally, display response rate may be hard to accurately determine. In some examples, display response rate may be determined by metrics maintained on the device whose rate is being measured. In other examples, display response rate may be determined by monitoring human interaction with the device, which may int...
